在Python中,字典(Dictionary)是一种非常常用的数据结构,它可以存储键值对,并且支持快速的查找操作。然而,普通的字典在遍历时并不会按照插入的顺序来进行,这就导致了在某些情况下并不能满足我们的需求。 为了解决这个问题,Python中提供了collections模块中的OrderedDict类,它可以按照插入的顺序来遍历字典中的元素。 使用Or...
在python中,dict,set等数据结构的key是hash无序的。有时候,我们需要得到排序的字典。 注意:OrderedDict的Key会按照插入的顺序排列,不是Key本身排序 实际案例: 有一些task,需要保存到字典中,key为名称,value为内容,但是执行的时候,需要保持存储时的顺序 In [1]: from collections import OrderedDict In [2]: od =...
